Hey i just bought a 600 watt hps in a cool tube 6 as soon as i turned it on all was well but about 20min in it started to smell like burnt plastic does this hood 100% have to be cooled by a fan or is there something wrong with my light? :(
I can go back to my other light for the time being but the sooner i can get a response the better. tnx

if its in a cool tube you have to have a fan on it. the plastic will get to hot right near a 600 watter

so just keep using my normal 400 till my inline fan gets here? will a 6inch inline fan keep it from smelling like this?

yeah you need to use your 400, what kind of inline fan, I hope its not an inline duct fan and actually a centrifugal fan with a descent cfm rating. I use a 6" 485 cfm with an adjustable speed controller

is 424cfm with a carbon filter on it going to be enough power for it? if not would removing the filter help fix that or still not enough? I also plan on getting a second 600 in cool tube, if i do so could i get a 6inch 424 for both of them or would each one require its own fan?

the room is 8x12 however i will be sectioning it off into to different tents with a plan of putting the 2 600s in a 4x8 x6.5 tent i had planned to use a 6inch 424 on the two lights and a second with a carbon filter on the room set to a controller with co2. set me strait here if im doing it wrong.
